THILL=COUPLING.

srnorrrcnrron forming part of Letters Patent No. 437,564, dated September so, 1890.

Application filed July 3, 189C). Serial No. 357,632- (No model.)

To all whom it may concern;

Be it known that I, FRANK A. BURTON, a citizen of the United States,residing at Charles City, in the county of Floyd and State of Iowa, have invented certain new and useful Im provements in Thill-Couplings; and I do declare the following to beafull, clear, and exact description of the invent-ion, such as will enable others skilled in the art to which it appertains to make and use the same, reference beinghad to the accompanying drawings, and to the letters of reference marked thereon, which form'a part of this specification.

Figure 1 represents a vertical sectional view of the invention, and Fig. 2 a perspective view of the combined pivotal bolt and anti-rattling spring.

The invention has relation to certain new and useful improvements in thill-couplings, and its objectand nature will fully appearin the course of this specification.

Referring to the annexed drawings by letter, A designates an axle, and B a clip secured to the same in the usual manner, and having formed on its front side the usual ears B, between which the eye of the shaftiron C is pivoted by the pin D in the usual way. This pin D has formed on one end a downward extension D, which is turned and bent inward under the shaft-eye, as at D, where it is formed into a flat spring E, bent so as to fit up in the space between the axle and shafteye and adapted to bear against and fit the latter. The end of the spring is turned downward and bears against the front side of the clip, ashouldered extension E being formed on its lower end, this shouldered end fitting over the front end of the cross-bar of the clip and preventing premature displacement.

This device will effectually prevent rattling, and at the same time allow the shafts a free movement. It does away with threaded bolts and nuts, and it is impossible to prematurely work loose, and at the same time is durable, cheap, and simple in construction.

To remove the shafts, it is simply necessary to raise them above their ordinary level, whereupon the springs will be forced out and the bolts or pins may be readily slipped out of the eyes.

Having thus fully described my invention, what I claim is- 1. The combination, with a clip and shaftiron, of a coupling-pin having formed integral with itself and projecting from one of its ends an extension, this extension being bent down under the shaft-iron and formed in a fiat spring, said spring fitting up between the shaft-iron and clip, substantiallyas described.

2. The combination, with' an axle, a clip secured thereto and provided with a pair of ears, and a shaft-iron having its eye fitting between the ears, of a coupling-pin passing through the ears and shaft-eye, and having formed integral with one of its endsa flat spring bent up into the space between the clip and shaft-eye and curved to fit the latter, the end of the spring being turned downward and formed into a shoulder to fit over the end of the clip cross-bar, substantially as described.

In testimony whereof I affix' my signature in presence of two witnesses.

FRANK A. BURTON.
